Setting up a service on the pi

From https://simonprickett.dev/writing-a-systemd-service-in-node-js-pi/

1. Create a service file e.g. levain-out.service
2. Run sudo cp levain-out.service /etc/systemd/system
3. Run sudo systemctl enable levain-out.service (this tells systemctl to enable on boot)

Other useful commands:

• Manually start a service: sudo systemctl start levain-out.service
• Reboot the pi: sudo reboot
• View logs for this service: journalctl -u levain-out or journalctl -u levain-out -f to tail the log
